A new organic-inorganic perovskite-type compound [(CH)PCHOH][CdBr] exhibits a ferroelastic phase transition at 339 K. Domain structures were observed and analyzed. The origin of the phase transition can be attributed to the motion or reorientation of the [(CH)PCHOH] cations and the displacement of Cd and Br ions in solid-state crystals.
一种新型有机-无机钙钛矿型化合物[(CH)PCHOH][CdBr]在339 K时呈现铁弹相变。对畴结构进行了观察和分析。相变的起源可归因于[(CH)PCHOH]阳离子的移动或重新取向以及固态晶体中Cd和Br离子的位移。
